You have got to be kidding, WeeNel. I've dug up 513 square feet of it and have gone down past a foot and there are still roots down farther. Round Up gives the look of having killed it but after many applications the very sad truth is that it returns. In warm weather it returns in 35 days and if killed in December it will return here in April. I have spent the last three months working at it all summer, 8 to 11 hours DAILY, and it's still there underground just waiting to erupt. I remove each piece and scour the surrounding soil (sifting it) to remove every last piece of it.

When I finish with what I can reach, without digging up the 50 year old pines and hiring a company to rip out these roots, I will put down heavy duty black plastic for a year, maybe two and maybe more than two years, to be sure it's gone forever.
